• The scope of the refrigeration system test procedure, particularly, identifying which refrigeration components fall within the scope of DOE’s walk-in regulations;

• the operation of the test procedure’s methodology, including the methods used to calculate defrost energy consumption;

• the application of the test procedure when rating different walk-in refrigeration systems (i.e., mixed versus matched systems);

• the calculation of the ratings of a given walk-in refrigeration system component when only component (i.e. the evaporator coil unit or condenser unit) is produced; and

• the AEDM requirements as they apply to walk-in refrigeration systems.

DOE encourages all interested persons to submit questions to DOE that are relevant to the above topics in advance of the meeting date to ensure that the agency is able to fully address these topics. As the intent of this meeting is to help manufacturers to better understand how to rate their equipment, DOE will not be discussing the methodology or analysis used in developing the recently amended energy conservation standards for walk-in refrigeration systems.

**Airworthiness Directives; Airbus Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2007–14– 05, for all Airbus Model A310 and Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). AD 2007–14–05 currently requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating certain certification maintenance requirements. Since we issued AD 2007–14–05, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program to incorporate more restrictive maintenance requirements and airworthiness limitations. We areproposing this AD to prevent safetysignificant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems.

Discussion

On June 26, 2007, we issued AD 2007–14–05, Amendment 39–15127 (72 FR 39307, July 18, 2007). AD 2007–14– 05 requires actions intended to address an unsafe condition on all Airbus Model A310 and A300–600 series airplanes.

Since we issued AD 2007–14–05, Amendment 39–15127 (72 FR 39307, July 18, 2007), we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. The European Aviation Safety Agency (EASA), which is the aviation authority for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0072, dated March 20, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

The airworthiness limitations for Airbus aeroplanes are currently published in Airworthiness Limitations Section (ALS) documents.

The airworthiness limitations applicable to the A300–600 and A300–600ST Certification Maintenance Requirements (CMR) were previously specified in the Airbus A300–600 CMR document referenced AUST5/829//85. DGAC [Direction Ge  ́ ne

_ad

_F

_2005

_ 123.pdf/AD

_F-2005-123 (EASA approval 2005–6070) [which corresponds to FAA AD 2007–14–05, Amendment 39–15127] to require compliance to the requirements as specified in this document. Since that AD was issued, the CMR tasks are now specified in Airbus A300–600 and Airbus A310 ALS Part 3 documents, which are approved by the European Aviation Safety Agency (EASA). These documents introduce more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with the maintenance requirements contained in these documents could result in an unsafe condition.

For the reasons described above, this new [EASA] AD retains the requirements of DGAC France AD F–2005–123, which is superseded, and requires the implementation of the new or more restrictive maintenance requirements as specified in Airbus A310 ALS Part 3 Revision 00 and A300–600 ALS Part 3 Revision 00, as applicable to the aeroplane type/model.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014–
0655.

Relevant Service Information

Airbus has issued A310 ALS Part 3, Certification Maintenance Requirements (CMR), dated November 30, 2012. Airbus has also issued A300–600 ALS Part 3, Certification Maintenance Requirements (CMR), dated April 18, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance

We estimate that this proposed AD affects 156 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

### 59156 Federal Register / Vol. 79, No. 190 / Wednesday, October 1, 2014 / Proposed Rules

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this proposed regulation:

1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866;

2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701. **§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2007–14–05, Amendment 39–15127 (72 FR 39307, July 18, 2007), and adding the following new AD:

**Airworthiness Directives; Bombardier, Inc. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports of cracking on the skin panels and skin splice joints and angles at certain stringers at various locations between certain fuselage stations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance requirements and airworthiness limitations, and incorporating structural repairs and modifications to preclude widespread fatigue damage (WFD). We are proposing this AD to detect and correct WFD, which could adversely affect the structural integrity of the airplane.
